Description

We offer to purchase a Lian Li power supply unit with a power capacity of 750W, which has received the 80 PLUS Bronze energy efficiency certification.

With 750W power, it will be sufficient for a good mid-level gaming experience. The power supply unit will be able to run a computer with a high-class processor, a powerful mid-range graphics card (for example, RTX 4070), and several drives (SSD/HDD).

This power supply is equipped with an exceptionally large 135 mm fan. Thanks to the larger blade size, it provides better airflow at lower speeds and quieter operation compared to standard 120 mm fans.

The power supply has been awarded the 80 PLUS Bronze energy efficiency certificate, which ensures at least 85% efficiency at 50% load. This indicates that at least 85 W out of 100 W of power received by the power supply from the electrical grid is delivered to the computer components, with the remaining 15 W being lost as heat.

The color of this power supply is Melna. The cable color is Melna and they are flat.

This power supply unit does not have modular cables – all its cables are attached to the unit and are not detachable. Despite the simple design, it will fulfill its functions just as well as a power supply unit with modular cables.
